Revised August-2017 Glossary A-1
Appendix A – Glossary
Note: This is a generalized glossary of terms. Not all the terms may
necessarily correspond to the particular device or software
described in this manual. For that reason, the term “ROC” is
used to identify all varieties of Remote Operations Controllers
(including ROC800-Series, ROC800L, DL8000, FloBoss™
107, and FloBoss
™
100-Series). Refer to Measurement Units,
Symbols, and Abbreviations (Form A6302) for additional
information.
A
Analog to Digital signal conversion.
Acrylonitrile Butadiene Styrene.
Analog to Digital Converter. Used to convert analog inputs (AI) to a format the flow
computer can use.
American Gas Association. A professional organization that oversees the AGA3
(orifice), AGA5 (heating value), AGA7 (turbine), AGA8 (compressibility), AGA9
(Ultrasonic) and AGA11 (Coriolis) gas flow calculation standards. See
http://www.aga.org.
Analog data is represented by a continuous variable, such as an electrical current
signal.
American Petroleum Institute. See http://www.api.org.
A user-defined grouping of database entities.
American (National) Standard Code for Information Interchange.
A parameter that provides information about an aspect of a database point. For
example, the alarm attribute is an attribute that uniquely identifies the configured value
of an alarm.

Bits Per Second, associated with baud rate.
British Thermal Unit, a measure of heat energy.
I/O channels that are fabricated into the ROC and do not require a separate option.
Also called “on-board” I/O.
Class 1, Division 2 hazardous area
